As of now, the lead speculation is that it will be a Sith Eyes Anakin. From all the hints, and the fact that usually the SDCC SSC Exclusive is some kind of retool/variant of an existing figure, that's my best guess. It would make the most sense, since it would be a simple eye repaint, some tattering/burn damage on the clothing, and knowing they have SDCC coming up produce a slight retool of the existing head cast to give him more of a "messed up" look. Remember the old adage "Why make one, when you can make two for the price of one".

If memory serves me right, I believe Dave Myatt said somewhere that it won't be a Han or Luke, or any figure in current 1/4 format. Take what you will from it, but here is a little interesting tidbit: (sixth question from the bottom)

Well i woul dlike to throw my name in the hat for someone who needs help getting one. I can never afford to make it out there so if anyone get me one it wopuld be greatly appreciated. My guess it will be something cool that we will all want instead of something simple.

Well if they do make a SDCC exclusive hopefully they will do what they did last year and that was they made like 20% or so of the edition size available for pre order on their site to people who are not attending the con.

In the collectible action-figure arena, Sideshow Collectibles of Westlake Village, Calif., is continuing with an aggressive push to expand its Star Wars line for 2006. Brant Bridges, production manager at Sideshow, told SCI FI Wire: "We did the Premium Format line and more recently introduced the 12-inch line, and we have been rabidly focused on it. We've broken the line into five sub-collections called Order of the Jedi, Heroes of the Rebellion, Lords of the Sith, Military and Scum and Villains. Because the line has been so successful, we are looking to branch out in ways collectors should be very happy about. Star Wars is where we will venture into unique body-shape figures—some of the creatures, the droids and the stormtroopers—we are going to tackle them."

Revealing their announcement lineup, Bridges added: "We have Mace Windu and Empire Han Solo here at Toy Fair. Then we are shipping the first 10 figures this year. We are planning a San Diego [Comic-Con International] exclusive figure, which was going to be Kit Fisto, the alien Jedi from the last two prequels, but reaction was so strong to Luke and Anakin, we decided an entirely unique character would upset collectors. For the [Comic-] Con exclusive, it will be a legitimate variation on an existing character."

So, at least that is more confirmation that the SDCC figure will just be a variation and probably strengthens the "Sith Eyes" Anakin rumors a bit...

From what I hear from people who have purchased SDCC SSC Exclusives, is that you pre-order on their site, and pick it up at the con. Only the person who ordered it can pick it up.

Sideshow has confirmed with us that this will be the case for the 2006 SDCC exclusive 12" Star Wars figure as well. You'll be able to order it ahead of time and then just pick it up at the show at the Sideshow booth - nice and neat.

They did not have any info on if any of the exclusives would be held back to sell to people who couldn't attend the show though...

Considering no one knows for sure what figure it is, I'm amazed how many people are sure it's Sith Eye'd Ani. I'm not going to confirm or deny, but there are a few other things it could be... Smiley Face Kit? Mustafar Obi-Wan? Endor Poncho luke... Carbonite Prisoner Han... TPM Mace (with proper Ep I belt)... Bad Dream Ani...

What I will say is there is a good chance I might have listed the figure above... But you can never tell with me.
